# Question: A single slit is illuminated with monochromatic light and a

A single slit is illuminated with monochromatic light, and a screen is placed behind the slit to observe the diffraction pattern.

(a) If the width of the slit is increased, will the width of the central maximum (1) increase, (2) remain the same, or (3) decrease? Why?

(b) If the width of the slit is 0.50 mm, the wavelength is 680 nm, and the screen is 1.80 m from the slit, what would be the width of the central maxi-mum?

(c) What if the width of the slit is 0.60 mm?
